The Angulation as to the Location of the Lag Screw of Compression Hip Screw in the Intertrochanteric Fracture of the Hip: Sang Won Park, Kwang Jun Oh, Seung Yong Wang; J Korean Soc Fract 2002;15(1):15-20. Published online January 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.1.15

Abstract PDF: PURPOSE
The purpose of this study was to evaluate the change of the angulation deformity according to apposition of medial cortex and sliding mechanism as to the location of the lag screw in the intertrochanteric fracture of the Korean femur which neck-shaft angle is relatively small .
MATERIALS AND METHODS
We selected the patients those angulation of femur neck-shaft was within 5 degree in comparison with normal side, and displacement of fracture fragment was within 4mm on the immediate post-operative radiograph. According to Evans classification, all patients were type I fracture. We classified the patients in two groups -stable medial cortex apposition(Group I) was 13 cases, and unstable no apposition(Group II) was 16 cases.
RESULTS
In the Group I, the varus-valgus angulation was average 3.3 degrees when lag screw was positioned at the middle of the femur neck, average 3.6 degrees when lag screw was positioned at the inferior to the femur neck. In the Group II, the varus-valgus angulation was average 6.1 degrees when lag screw was middle of the femur neck, average 1.5 degrees when lag screw was inferior to the femur neck.
CONCLUSION
There is no difference in angulation deformity when the lag screw is inferior or middle of femur neck if medial cortex is contacted, but the angulation deformity is less when the lag screw is inferior to femur neck if medial cortex is not contacted, in intertrochanteric fracture.

Femoral Fracture Malalignment following Interlocking Intramedullary Nailing: Yeub Kim, Yong Beom Jeon, Gi Jung Joo, Hae Ryong Hur; J Korean Soc Fract 1999;12(1):61-68. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.61

Abstract PDF: Interlocking intramedullary nailing has become a common method of treatment for femoral shaft fractures in adults. But sometimes the malalignment of the femoral fracture results in pain, limb length discrepancy, and traumatic osteoarthritis of the knee, etc. Therefore, it is very important to know what makes the malalignment after the femoral shaft fractures. We performed CT scan in 46 patients who had femoral shaft fractures, treated by interlocking intramedullary nailing at the orthopaedic department of the Kwanaiu Verterans Hospital. There were thirty-five men and eleven women, and their mean age was 36 years at the time of the operation. We measured the rotational deformity of both femurs by the CT scanning and the angulation deformity by plain radiographs in forty-six patients. We also compared the amount of the angulation and rotational deformity according to the type or the site of fracture, the degree of comminution, the time from injury to operation and the associated injury. Average angulation deformity was 2.7degrees in sagittal plane and 2.5degrees in coronal plane. Average rotational deformity wat 10.2degrees Fourteen patients(30%) had angulation more than 5degrees Ten patients(22%) had rotational deformity more than 15degrees Angulation deformity was severe significantiy at proximal 1/3 fracture, segmental fracture and severely comminuted fracture group. But because there was no significant difference of rotational deformity according to the level of fracture, the amount of comminution, and associated injury, increased rotational deformity seems to be resulted from the preoperative traction and the intraoperative technique. Therefore, we must determine the accurate entry point of intrameduiiary nailing and reduce the fracture accurately by intraoperative ultrasonography or fluoroscopy.

Measurement of Angulation after Treatment of Fractures of the Tibia: Comparison of Conventional Methods and New Method Using Mechanical Axis: Chul Yong Chung, Chan Young Son, Sun Bon Koo, Sang Eun Kim; J Korean Soc Fract 1998;11(4):912-917. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.912

Abstract PDF: The importance of residual angular deformity after tibial fracture is still uncertain. but it is generally assumed that osteoarthritis of the ankle and the knee will result when the deformity is severe. Therefore accurate measurement of the alignment of the tibia is important clinically and in research. We compared the results of conventional methods (method 1,2) of measuring the angulation deformity after a fracture of the shaft of the tibia, with a new method using mechanical axis reported by Milner11) (method 3). Sixty-seven patients of tibial fractures with angulation deformity treated at sei Gang General Hospital from January 1995 to December 1996 were evaluated. Samples of 20 sets of standard AP and lateral radiographs of both tibia were measured. The results obtained were as follows. 1. The difference between the angles obtained by Milner's new method (method 3) and conventional methods (method 1,2) was significant in all planes. 2. Both the mean intra-& interobserver difference were minimal in new method, compared with conventional methods, t all planes. 3. There is no statistically significant difference using by paired T-test between angles obtained by new method and conventional methods (p>0.05). From these results, an angulation of measuring the new method was accurate and has good inter- and intraoesrver reliability.

Remodelling and Reangulation following the Fracture of Both Bones of the Forearm in Children: Sung Tae Lee, Jeong Hwan Oh, Eui Hwan Ahn, Hyuck Jun Lee; J Korean Soc Fract 1997;10(4):972-978. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.972

Abstract PDF: One-hundred fifty children underwent closed reduction for the fracture of both bones of the forearm were retrospectively reexamed with an average follow-up time of 28.7 months(range, 13-60 months). Patients were divided into three groups of 50-complete fractures, 50-green-stick fractures broken intact cortex and 50-green-stick fractures preserved intact cortex. The rate of the reangulation after closed reduction was lowest on the green-stick fractures preserved intact cortex. Forty-seven patients with residual angulation after healing were divided into two age groups of 4-10 years and 10- 15 years at the time of fracture. In children younger than 10 years of age with residual angulation after distal fractures of both bones of the forearm, the change of orientation of the epiphyseal plate toward the normal seemed to account for nearly all the actual correction at the site of fracture. The hinge should be used to aid in an accurate and stable reduction. The importance of the orientation of the epiphyseal plate is related to the distance between the fracture site and the epiphyseal plate according to the age of the patient.

Angulation Deformity Following Interlocking Nailing for Treaeent of Tibia Fracture: Hong Jun Han, Jae Hoon Shin, Jeong Hyu Lee; J Korean Soc Fract 1996;9(4):1002-1008. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.1002

Abstract PDF: Intramedullary nailing is often the treatment of choice in the management of fractures in the tibial diaphysis. With the advent of interlocking nailing, the indication for nailing have expanded, recently. One of the most frequent but little discussed complication of tibial nailing is fracture malalignment leading to angular or rotational deformities. This retrospective study was undertaken to access the incidence of aneular malalignment after interlocking nailing for 210 tibiae(208 patients). The results obtained were as follows; 1. The incidence of angular malalignment was 12.4% 2. The incidence of angular malalignment was 15.8% in proximal one third, 4.1% in middle one third,20.7% in distal one third fractures. 3. The most frequent deformity was valgus angulation in distal one third fractures. 4. Angular deformity was developed more frequently in cases of unlearned nailing(18.9%) than reamed nailing(8.4%). 5. Angular deformity was developed more frequently in cases of double level fracture(22.2%) than single level fracture(11.5%).

Treatment of Radial Head and Neck Fracture in Children: Hyung Ku Yoon, Kuk Hwan Oh, Kyung Hoon Kang, J I Kim, Jong Hwa Yi; J Korean Soc Fract 1996;9(3):688-694. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.688

Abstract PDF: Fracture of radial head and neck in children is a relatively rare injury and comprises 5 to 10 percent of fractures of the elbow in children. Its prognosis has been considered relatively good, but prognosis is poor in severely displaced fractures of the radial head and neck, especially types II and III by OBriens classification and have a high risk of complication. We retrospectively reviewed 8 cases of radial head and neck fractures in 1 patients, who were treated from Jan.1992 to June 1994 at Kwang Myung Sung Ae Hospital. They were followed up for more than 1 year. The results were as follows; 1. There were 4 male and 3 female patients. One patient had bilateral involvement 2. The most common cause was fall down injury (6 cases). 3. According to O'Briens classification, 3 cases were type I and 5 cases were type II Treatments included simple immobilization(3 cases), closed reduction and plaster cast (4 cases), percutaneous K-wire leverage method(1 case). 4. According to the criteria of Tibone, the clinical result was excellent in 7 cases and good in 1 case. Primary angulation was the most important factor affecting the result and early closed reduction was important to obtain the satisfactory clinical result.
